Coal Grinding. To achieve good combustion and satisfactory flame formation, coal needs to be dried and ground to a proper degree of dryness and fineness. Drying of moisture in coal is achieved normally by ducting part of the kiln exhaust gas through the mill with inlet temperatures of up to 300°C. Inert kiln exhaust gases with oxygen content ...

Most phosphate processors choose airswept milling systems due to their ability to remove fine particles from the grinding zone. Due to the cushioning effect from newly introduced feed, this allows the grinding action to be concentrated on the large oversize particles. This results in higher yields and, by minimizing overgrinding, lowers energy consumption.
